This will definitely help you:

https://github.com/twigphp/Twig/issues/3534

Try this solution :

public function jsonSerialize()
{
    if ($this->options === null) {
        $options = $this->collection->toOptionArray();
        $this->prepareData();
        foreach ($options as $optionCode) {
            $this->options[$optionCode['value']] = [
                'type' => $this->data['type'] . $optionCode['value'],
                'label' => $optionCode['label'],
            ];

        if ($this->urlPath && $this->paramName) {
            $this->options[$optionCode['value']]['url'] = $this->urlBuilder->getUrl(
                $this->urlPath,
                [$this->paramName => $optionCode['value']]
            );
        }

        $this->options[$optionCode['value']] = array_merge_recursive(
            $this->options[$optionCode['value']],
            $this->additionalData
        );
    }

    $this->options = array_values($this->options);
}

return $this->options;
